Fig. 3'is a top view of the hinged expanding sectional hopper, showing the series of diagonal ridges or irregularities ct a ct a a and the crushing drum or cylinder, with series of ridges or irregularities p p p p p, and the longitudinal parallelgutters or troughs s s s s.- To enable others to be skilled in the use and application ofour invention and improvements, we will proceed to describe the construction and operation thereof, the nature and principles ot' which consist in constructing a lime or compost spreader, Fig. 1, and arranging the same on an ordinaryT running-gear of two or more wheels, A A, Fig; l.

This spreader is formed of a body or box, B B B B, having a reservoir forlime, or a connpost-ohamber, C, and an implement-chest, D. We then have constructed a sectional expand` ing hopper, E E, hingedor hung on pivots by its upper edge, and having formed on its inner surface diagonal ridges or irregularities c a a a a, Fig. 3. We then have a cylinder or drum, F F, with a series ot' ridges or irregularities, p p p p 19, Fig. 3, formed diagonally across the periphery or circumference thereof. There are also formed at intermediate distances between the ridges longitudinal and parallel troughs or gutters s s s s, Fig. 3.

With regard to the particular form `of construction of the grinding-surface of the cylin'- der, Fig. 3, the following advantages and utility are embraced therein and a new result produced, viz Because ofthe obliquely-arranged ridges or furrows p p p p emptying into the horizontallyformed gutters or troughs s s s s the pulverized particles do not escape and fall together in as great a volume or compact mass as they would if there were no such formation of gutters or longitudinal troughs s s s s, for it A will be readily perceived that these troughs catch a portion of the pulverized mass and throw it ont gradually as the cylinder revolves over, thus distributing or spreading with more regularity or equality than could be otherwise done with plain tluted cylinders, such as are used generally' in compost spreading or distributing machines. rFhis cylinder, Fig. 3, revolves within and parallel to the faces or in ner surfaces ofthe expanding sectional hopper, Fig. 3. Now the advantage of this hopper is that, owing to its acting in combination with the cylinder, Fig. 3, an additional duty or function is embraced by regulatingthe coarseness or neness of deposit, as well as of graduating or regulating the supply ot' deposit in increased or diminished quant-ities, aided by the spring b b b b, Fig. 2, and screw 1th, Fig. 1.

Next is formed an open-bottom detachable fountain, Gr, having arranged upon its-top a hinged frame with a grating or succession ot' bent or curved rods or bars, as shown in Fig. l 'at o c c c c c. The utility of this grating is seen at once, for it is a weltknown fact that in all compost or lime there are more or less of hard and lumpy portions, and therefore the lumps must be prevented from choking or falling onto and between the cylinder and expanding hopper, Fig. 3. The object therefore of this hinged grating c c c c c is to admit of the ,throwing oif the lumpy portions, which is readily done by pulling the cords t' t' which 4pass over the pulleys J J of the cranes K K, through which the hinged grating c c o c o o is tilted or thrown up and forward, the cranes K K, Fig. l, answering as rests when the lumpy portions, rock and trash, are deposited on -the ground, after which the hinged-frame grating can be thrown back in its place again.

Within the open-bottom fountain Gr and bel roller, F F, with series of ridges or sloping neath the grating c c o c is arranged a horizontally revolving' feeding and pulverizing spike-shalt, H. This shaft and the drum or cylinder F gear into each other by the Wheels d d e c, and are driven by the driving-Wheelf, Fig. 1. There is arranged on the side of the frame or box B B a gearing and ungearing device, g g.

The operation of our compost-spreader is as follows: A supply ot' compost is put into the reservoir or receptacle C and the fountain Gr is filled with lime or compost, and the machine being attached to one or more horses by shaft or tongue. the machine is set in motion, the gearing-wheels d d e e being put in action by the driving-wheel or motive-wheel A, and thus the cylinder F F and spike-shaft H are made to revolve, the compost or lime in pulverized forni passing off through the bottoni of the eX- panding sectional hopper and distributed over the soil.

Havingthus fully described the construction and operation of our lime-spreader or compostmachine, what We claim as of our invention, and desire to secure by Letters Patent of the United States, is as follows, viz:

l. The construction of an expanding sectional hopper, E E, Figs. l and 3, hung by hinges, or otherwise pendent, and formed with concaves on the inner sides, which -concaves have formed thereon diagonally arranged ridges or sloping irregularities a a a a a a a, su listautially as described.

2. The construct-ion of a drum, cylinder, or

irregularities p p p formed or arranged diagonally across its circumference or periphery, together with longitudinal troughs or gutters s s ss at intervals between theridges, as shown at Figs. l and 3, this cylinder being also coinbined in action or operation with the hopper E E, Fig. l, and the revolving spike-shaft H, as set forth.

3. Ve are aware that there are such devices` as tilting tables, dumping beds and cart-bodies and sloping or sliding planes for the purpose oi'precipitation. Noneofthese,however,dowe claim, as they are not equivalent forms of construction to ours, for they do not embrace the twofold principles of our device. Noris it a fixed sieve or permanently-arrangcd grating that We claim; but instead We claim constructing a feeding or supply fountain having the combination of an adjustable hinged-frame grating actuated by cords or equivalents and to answer the twofold purpose of holding the compost mass and preventing the escape of lumps, &c., and admitting also of being elevated or depressed or thrown forward at pleasure for the purpose of relieving' the grating and hopper or fountain of lumps and other obstructions, in the manner and for the purpose set forth.
